Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a new energy high-current female connector. Background Technology

[0002] Connectors, also known as mating parts, are core components in electronic equipment, automobiles, industrial control, and other fields that enable the transmission of signals and power from wire harnesses. They form a circuit connection by mating male and female connectors. Female connectors are also frequently used in the field of new energy vehicles. They typically include a housing and terminals. The housing includes a mating part to accommodate the terminals and a slot for engaging with the male connector. However, most existing female connectors use a single sealing structure or lack reliable installation positioning and abutment limit design for the seals. This leads to easy displacement of the seals and a decrease in sealing effect after aging. In harsh environments such as humid and dusty conditions, moisture, dust, and other impurities can easily penetrate into the connector through the mating gaps or the wire harness exit points, affecting the service life and transmission reliability of the female connector. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a new energy high-current female connector with good sealing performance, ensuring service life and reliability.

[0004] To achieve the above objectives, this utility model provides a new energy high-current female connector, including a housing and terminals. The housing includes a plug-in portion and a slot. The terminals are installed in the plug-in portion. The slot surrounds the plug-in portion. The housing also includes a rear groove, a sealing cover, a first sealing element, and a second sealing element. The first sealing element is disposed in the slot and sleeved on the plug-in portion. The rear groove is internally connected to the plug-in portion. The second sealing element is disposed in the rear groove and has an inner hole for the wire harness to pass through. The sealing cover is inserted into the rear groove and forms abutment and limiting of the second sealing element.

[0005] The advantages of adopting the above technical solution are: by setting a double sealing structure in the housing, the sealing performance of the new energy high current female connector is improved. The first sealing element is sleeved on the plug part and embedded in the slot, which can tightly fit the plug surface of the male connector to block external gaps. The second sealing element is positioned by the rear groove and abutted and limited by the sealing cover, which can firmly wrap the wire harness protrusion part, thus forming a double sealing structure. The plug-in setting of the sealing cover not only prevents the second sealing element from shifting or falling off during long-term use, but also ensures the neatness of the wire harness arrangement and the stability of the terminal installation environment, taking into account both sealing effect and reliability.

[0006] The present invention can be further configured such that: the housing includes an upper groove with a connecting slot and a snap-fit ​​part located in the groove, the snap-fit ​​part is provided with an operation key, the operation key can be pressed to drive the snap-fit ​​part to swing elastically, the snap-fit ​​part can swing or reset to release or form a snap-fit ​​engagement with the male connector inserted into the slot.

[0007] By further configuring the upper slot of the connecting slot and the locking part with the operation key inside the slot, the reliability of the locking and engagement between the new energy high current female connector and the male connector is ensured. The operation key only needs to be pressed to drive the locking part to swing and unlock, making the subsequent removal of the male connector less strenuous and taking into account the ease of operation.

[0008] The present invention can be further configured such that: a locking member is provided at the snap-fit ​​part, the locking member is slidably sleeved on the snap-fit ​​part and includes an abutment part located below the operation key.

[0009] By further designing the locking element with a stop portion, which is slidably fitted onto the snap-fit ​​part and positioned below the operation key, the stop portion and the operation key are positioned to limit the operation and prevent accidental touch or pressure during use, thus ensuring the stability of the connection between the male connector and the new energy high-current female connector.

[0010] This utility model can be further configured such that a limiting protrusion is provided below the abutting part.

[0011] With further configuration, after the male connector and the new energy high-current female connector are fully engaged, the limiting protrusion can position the locking component to prevent it from accidentally coming off.

[0012] The present invention can be further configured such that: the housing includes a lower opening and a terminal limiting member, the terminal limiting member can extend into the insertion part through the lower opening, and the terminal limiting member includes a locking head for forming a limiting engagement with the terminal.

[0013] By further designing the terminal limiting component, it extends into the insertion part through the lower opening, and the locking head forms a limiting engagement with the terminal to lock the terminal position. This prevents the terminal from becoming loose or shifting due to vibration or increased insertion and removal times, avoiding subsequent poor contact that could affect signal or power transmission, and improving the overall lifespan and transmission reliability of the connector.

[0014] The present invention can be further configured such that: the terminal limiting member includes an adjusting part, the adjusting part is provided with a first groove and a second groove in sequence, and a locking block is provided on the inner wall of the lower opening, the locking block can extend into the first groove or the second groove to form a locking limit.

[0015] By further configuring the terminal limiting member, the first and second grooves, along with the locking block on the inner wall of the lower opening, form a switchable locking limit. By adjusting the position of the locking block in the first and second grooves, the position of the locking head is adjusted. In the first groove, a preliminary limiting effect is achieved, allowing the terminal limiting member to connect to the housing. After the terminal is installed in the housing, pressing is then used to move the locking block into the second groove to complete the installation.

[0016] The present invention can be further configured as follows: there are two adjustment parts, which are respectively arranged on both sides of the card head and extend in an inclined direction; the terminal limiting member is provided with ears on both sides, and the ears can be inserted into the plug-in part with the card head to form a fit with the outer wall of the plug-in part.

[0017] By further configuring the adjustment mechanism with an angled extension and adding ears on both sides, the adjustment part can be aligned by installing the ears, releasing the first or second slot from the locking block and facilitating removal. The ears can also be inserted into the connector along with the locking head to form a close fit with the outer wall of the connector. This ensures that after the male connector and the new energy high-current female connector are properly connected, the ears are positioned to prevent them from accidentally dislodging the adjustment part during use, thus enhancing positioning stability.
